Soil that is healthy is fertile and productive. [29] But soil erosion leads to a loss of topsoil, organic matter, and nutrients; it breaks down soil structure and decreases water storage capacity, reducing fertility and water availability to plant roots. Soil erosion is, therefore, a major threat to soil biodiversity. [30]
The Biodiversity Heritage Library (BHL) is the world’s largest open-access digital library for biodiversity literature and archives.BHL operates as a worldwide consortium of natural history, botanical, research, and national libraries working together to address this challenge by digitizing the natural history literature held in their collections and making it freely available for open ...
Biodiversity loss happens when plant or animal species disappear completely from Earth or when there is a decrease or disappearance of species in a specific area. Biodiversity loss means that there is a reduction in biological diversity in a given area. The decrease can be temporary or permanent.
The World Wildlife Fund’s Living Planet Report 2022 found that wildlife populations declined by an average 69% since 1970. [1] [2] [3]The Living Planet Index (LPI) is an indicator of the state of global biological diversity, based on trends in vertebrate populations of species from around the world.
Gap analysis is a tool used in wildlife conservation to identify gaps in conservation lands (e.g., protected areas and nature reserves) or other wildlands where significant plant and animal species and their habitat or important ecological features occur.
[26] [27] Around 25% of the planet's ice-free land is being used to rear cattle for human consumption. [10] In the ocean, overfishing is a major cause of species loss. [16] [27] Some 300–400 million metric tons (660–880 billion lb) of heavy metals, solvents, toxic sludge, and other wastes per year enter the water cycle from industrial ...
It overcomes the shortcomings of biodiversity indices that cannot display the relative role different variables played in their calculation. The curve is a 2D chart with relative abundance on the Y-axis and the abundance rank on the X-axis. X-axis: The abundance rank. The most abundant species is given rank 1, the second most abundant is 2 and ...
